1N5369BE3/TR13

Overview

The Microchip Technology 1N5369BE3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333B-1N5388B series. It provides voltage regulation at a nominal Zener voltage of 51 V with a ±5% tolerance, indicated by the 'B' suffix. The device operates within a temperature range of -65°C to +150°C and features a maximum reverse leakage current of 500 nA at 36.7 V. Packaged in an axial T-18-2 case with RoHS-compliant e3 plating, it is supplied in tape and reel format per EIA-296 standards.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole integration

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High current applications with adequate heat sinking
• General purpose electronic equipment protection

Procurement Notes

Verify the component status as this part may be discontinued or subject to production changes. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration. Ensure compliance with environmental directives such as RoHS and REACH before finalizing procurement specifications.

Selection Notes

Select this component when a 51 V reference with tight ±5% tolerance is required. Consider the thermal resistance characteristics and derating curves for high-power operation. Verify that the axial lead form factor aligns with the target printed circuit board layout and assembly requirements.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage selection from 3.3 V to 200 V. The 'e3' suffix denotes RoHS compliance, while the 'TR13' indicates tape and reel packaging.

Replacement Considerations

SMBJ5369A is listed as a parameter-equivalent surface mount alternative.
